Sergio U. Aguirre

In loving memory of Sergio Ulisses Aguirre also known as "Serg", with sadden hearts we announce his sudden and unexpected passing on August 3, 2025, at the young age of 39.

A loving son to Alvaro Aguirre, and Zeferina Martinez, and a wonderful brother to Maria Guadalupe, Erika, Gilberto, Jessica, Yvonne, Celeste, Michael and Samael. Serg was a loving father and fun cousin, a devoted and faithful friend to many, a great uncle always teaching them lessons by his mistakes-- what not to do. He was a hard worker who was known to speak his mind, true to himself always.

Known as a free spirited soul who loved to travel and explore the world traveling from state to state in his spare time. Known to love being outside in nature, he also loved creating and listening to music, he loved his dogs as faithful companions always by his side. He loved bringing smiles to all with his silly jokes and sarcasm, but above all known for his deep love for his 3 beautiful daughters, who were always on his lips and heart. Imanii was first born, 13 years old at time of his passing, Natalia 9, and Viviana 6 they were, are, and will always be his world. 

He was always known as an entrepreneur who could accomplish the most in the shortest amount of time he was given, with 20 years plus of experience in painting and construction. Although he didn't accomplished all that he wanted with the short time given to him, he did manage to leave the biggest treasure behind which is a piece of him through his 3 daughters, to be watched over not only by their mothers but also by his immediate family (siblings) so that they can have a piece of their dad here on earth with them forever until they see him one day in heaven again and reunited not only with them, but with all his family. He will always be loved, remembered, and cherished in our hearts forever, this is not a good bye forever, but until then.... in Jesus name.

A celebration of his life will be held at: WITKOWIAK FUNERAL HOME, 529 W. Historic Mitchell Street, Milwaukee, Wisconsin on Saturday August 9, 2025 from 5 PM to 7 PM.

In lieu of flowers, donations may be made to either María Guadalupe or Erika Quinones, any and every donation is appreciated with all our hearts and we are very thankful to all who have helped in a short amount of time, may the Lord bless you 10 fold for helping in a time of need.
